SPECTACLES.

Specification of lLetters Patent.

Patented Dee. 31, i918.

application nea June 1,1918. serial No. 237.7455.

To all whom t may concer-a.'

Be it known that l, CLAUDE Moonn, a citi- Zen of the United States ot'America, and a resident of Cedar Rapids, Linn county, iowa, haveinvented cert-ain new and useful improvements in Spectacles, o' whichthe following isa specification.

My invention relates to improvements in spectacles, and the object ot'my improvement is to supply for the use of chauffeurs and othersspectacles having colored glasses hinged to open trames and providedwith adjustable means for holding them in desired inclined positionsIrelative to said frames, or secured in a closed position relativethereto,

This object l have accomplished by the means which. are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, in which Figure 1 is a perspective .view of a pair ot myimproved spectacles, showing the hinged glasses raised to an adjustedinclined position relative to their open frames, and Fig. is an endelevation ot' the same, the full lines indicating the raised position ofsaid glasses, and the dotted lines the lowered position of the same. 1

Similar numerals of reference denote corresponding parts throughout theseveral views.

My `improved spectacles have rectangular open frames 1 rigidly connectedin the usual spaced relation by means ot a nose-piece 4 and a cross-bar5. Bows 7 are in the usual manner hinged at the middlcs ot' the outerup'rigl'it bars of said frames to swing toward each other. rlhe numeral2 denotes a pair of colored. tinted or smoked glasses ot rectangularform of dimensions suitable to cause them to cover the openings of theframes 1 ,when lowered, and are hinged toV the top bars of said tramesat 3.

I have supplied the following` means for holding said glasses at anadjusted angle relative to said frames. rllhe glasses are rig idlyconnected by a cross-bar 6 so as to move together Without deiection. Onone of the outer side bars of one frame 1 is a fixed pintle 8 upon whichis pivotally mounted one end of a curved rack-bar 10. At an oppositelocation on the adjacent glass 2 is ixed a loop 11 through which thetree end ofi said rack-bar ent-ends movably.

The detente ot said rack-bar detachably engage thelowcr member of saidloop, and

are kept in engagement therewith by means of a small bar-sprin 9, one enof which is secured to said pint e 8, and its other end bearingresiliently upon the top of said rack-bar. The positions of the pivotalconnection of the rack-bar and said loop may be reversed to be mountedrespectively upon said glass and said frame, Without departing from myinvention.

The rock-bar may be manually lifted to clear its detents in adjustingthe angle of inclination of said glasses relative to said frames, andthen the said spring will hold it in engagement with the loop whenreleased, as also when in its lowered position, as indicated by thedotted lines in Fig. 2.

The glasses are rectangular to increase the .field of visiontherethrough, and are colored, tinted or smoked to dim the glare of' thesun when setting or rising, or of an approaching head-light or lights ona vehicle. 1n use, the glasses are usually raised to about the vangleshown in said figures, so that the user may look under them at closeobjects, while having his or her eyes protected from a glaring lightahead. the light being seen through the glasses. The inclination of theglasses may be adjusted by the means shown as necessary relative to aglaring light ahead, or entirely closed down.

@ther equivalenti-.means for holding the glasses in a certain. positionrelative to the frames may be used and still be covered by the principleof my invention.

Having described my invention, what I claim as new,` and desire tosecure by Let- 'ters Patent, is:

1. The combination with a 'pair of open spectacle-trames, of coloredglasses hinged to their top bars to' swing upwardly therefrom. and meansfor supporting said glasses at an angle relative-to said frames, cor-.rprising a rack pivoted to one ot said frames, engaging-means on theadjacent glass with which said rack detachably engages, and yieldableresilient means yieldingly holding said rack in engagement with saidengagingmeans.

2. The combination with a pair of open rectangular spectacle-trames, ofrectangular' colored glasses hinged thereto, and means for supportingsaid glasses at an adjusted position relative to said frames7 comprisinga rack pivoted to one of the frames, means on the adjacent glass forengaging said rack dctachably, and a spring bearing yieldinglyyieldingly l upon seid rack to retain it in an adjusted position ofengagement with the said e11- gagmg-meons.

3. The combination with a pair of open speeaceiremes, of glasses hingedthereto,

A and means for suppol'tng said ,glasses at de- Siled postionsrelatve tosaid frames, compmsmgeu erm plvoted on one of the trames m hevmgengagmg-means, a loop fixed on meme? the adjacent g1ass,the arm beingpassed 10 movably through said loop, its engaging means adapted toengage a part theeof detachably, and yieldable resilient Ineens foryeldingly holding' said arm in engagement with said loop.

1n testimony lwhereof ax my sgnetuxe.

CLAUDE MGORE.
